FAQ

Questions & Policies

Who is Sascha Das and how can I get in touch?
Sascha Das (also known as SASCHA X99) is a software engineer, cyber security analyst and the founder of DRC Esports, based in Bangladesh. Use the contact form below, or reach out by email, Telegram, GitHub or Facebook.
Do you offer post-project support?
Yes, I provide 1 month of free maintenance and bug fixing for every project I deliver.
What are your service limitations & ethical policies?
I strictly perform ethical security audits (VAPT) only on domains/apps you legally own or have written authorization for. Custom development scope is clearly defined before starting any project.
Is my data secure with your bots?
Absolutely. I follow strict data privacy protocols and use encryption to ensure user data remains safe.
Can you help manage my Esports team?
Yes! I have experience managing DRC and can help with branding, discord setup, and tournament management.
Do you design the UI/UX as well as write the code?
Yes. I design and build responsive, accessible interfaces from wireframe to launch, so the look, the speed and the code quality all come from one person.
Will my website be optimised for search engines?
Yes. Every site I build includes semantic HTML, fast loading, clean metadata, structured data (JSON-LD) and a mobile-first layout, which are the foundations of technical SEO.
How long does a typical project take?
A bot or landing page usually takes a few days to two weeks. Larger systems are scoped first, and you get a clear timeline before any work starts.
Which technologies do you work with?
Mainly PHP, Laravel, MySQL, Python, JavaScript and Tailwind CSS, plus Linux, Docker and Nginx for hosting. I pick the simplest stack that fits your project and budget.
Do you work with clients outside Bangladesh?
Yes. I work remotely with clients worldwide and communicate in English and Bengali by chat, email or Telegram.
What do you need to get started?
A short description of your goal, any existing accounts or designs, and your preferred deadline. I reply within 24 hours with questions and a clear scope.
How does pricing work?
Pricing depends on scope. After a short discussion you receive a clear written quote, so you know the cost and timeline before work begins.
Can you fix or redesign my existing website?
Yes. I review your current site for bugs, security gaps, speed and usability, then fix or redesign it without losing your content or search rankings.
Will you help my website appear on Google?
Yes. I set up Google Search Console, a sitemap and robots.txt, canonical URLs and structured data, and I fix the technical issues that keep pages from being indexed.
Do I get the source code and documentation?
Yes. Every project is handed over with full source code, deployment notes and a short walkthrough, so you are never locked in.
